A connector is for placing adjacent devices (2,3) in a head part (1) of a liquid treatment apparatus in liquid communication with each other. The head part devices (2,3) are of the type arranged to receive at least a connecting head (68) of a replaceable liquid treatment cartridge (4,5). A first of the head part devices (2,3) has at least one inlet port (12-14), at least one first outlet port (16,17) and at least one second outlet port (18). At least in an operational position of the liquid treatment cartridge (4), only the first of the first and second outlet ports (16-18) are in liquid communication with at least one of the inlet ports (12-14) via the liquid treatment cartridge (4) and the second outlet ports (18) are in liquid communication with at least one of the inlet ports (12-14). A second of the head part devices (2,3) has at least one first inlet port (19,20), at least one second inlet port (21) and at least one outlet port (22-24). At least in an operational position of the liquid treatment cartridge (5), only the first of the first and second inlet ports (19-21) are in liquid communication with at least one of the outlet ports (22-24) via the liquid treatment cartridge (4,5) and the second inlet ports (21) are in liquid communication with at least one of the outlet ports (22-24). The connector is one of: (i) positionable with respect to the head part devices (2,3) such as to place the first and second outlet ports of the first head part device (2) in sealed liquid communication with the second and first inlet ports of the second head part device (3), respectively; and (ii) positionable with respect to the head part devices (2,3) such as to place at least the first outlet ports of the first head part device in sealed liquid communication with the first inlet ports of the second head part device. The connector has at least two connector inlet ports (28,29) and at least two connector outlet ports (30-32). The connector includes a first flow conductor (50) interconnecting a first sub-set of the connector inlet ports (28,29) and a first sub-set of the connector outlet ports (30-32). The connector includes a second flow conductor (51) interconnecting a second sub-set of the connector inlet ports (28,29) and a second sub-set of the connector outlet ports (30-32). Flows of liquid through one of the first and second flow conductors (50,51) are kept separate from those through the other by at least one of the first and second flow conductors (50,51). The first and second flow conductors (50,51) are arranged so that the separated flows of liquid cross each other.

摘要:
There is provided a water treatment apparatus, including: first membrane filtration means in which a filtration membrane having an average pore diameter of 1 µm or more is used; second membrane filtration means for treating water filtered by the first membrane filtration means, by using a microfiltration membrane or ultrafiltration membrane; and reverse osmosis membrane filtration means for treating water filtered by the second membrane filtration means. In particular, there is provided a water treatment apparatus, wherein a hydrophobic polymer membrane that is not subjected to hydrophilicizing processing is used as the filtration membrane having an average pore diameter of 1 µm or more. There is also provided a water treatment method that can be implemented by these water treatment apparatuses.

There is described a fluid treatment system comprising: (i) a fluid inlet; (ii) a fluid outlet; and (iii) a fluid treatment zone in fluid communication with the fluid inlet and the fluid outlet. The fluid treatment zone comprises a housing within which is disposed a fluid separation section (the separation section may include a single separation device or a combination of two or more similar or disimilar separation devices) and a fluid radiation section in fluid communication with one another. The fluid separation section removes solids in the fluid and the fluid radiation section irradiates the fluid to deactive microorganisms in the fluid. The fluid separation section and the fluid radiation section are configured to have a substantially common fluid flow path which significantly reduces the space or footprint requirement of and/or significantly reduces hydraulic head loss (pressure drops) in the overall fluid treatment system while allowing the two sections to perform their respective functions.

A filtration and demineralization apparatus that is capable of reducing the cost of the apparatus and building cost by using an apparatus whose height is limited, and that is also capable of ensuring sufficient treatment capacity, as well as good operability, is provided. A filtration and demineralization apparatus 10 comprises a vessel 20 in a form of a body of revolution; a hollow columnar body 40 that is located in an internal space of the vessel 20, one end 40a of the columnar body being connected to an inner surface of the vessel 20 along an entire circumference of the end, and the other end 40b of the columnar body forming an opening; and a partition plate 44 that is connected to the other end 40b of the hollow columnar body along an entire circumference of the other end 40b, the partition plate being configured to separate an inside space or an outside space of the hollow columnar body 40 as an independent space in the vessel. The partition plate 44 has a circulation port 43 that allows water that is to be treated to pass therethrough. The independent space in the vessel that is separated by the partition plate functions as a filtration chamber 41 in which filter elements are loaded, and the inside space or the outside space of the hollow columnar body that is not separated as the independent space by the partition plate functions as a demineralization chamber 22, the water that was treated in the filtration chamber being adapted to enter the demineralization chamber through the circulation port 43.
摘要:
The invention relates to a filter device (10) for filtering a liquid, especially a hydraulic oil. The inventive device comprises an essentially cylindrical filter housing (12) which receives a filter element (30) and can be closed by means of a lid (18). Said filter element (30) is associated with a non-treated area (70) having an inlet (22) for supplying liquid to be filtered and a treated area (74) having an outlet (26) for evacuating filtered liquid. The filter element (30) comprises an end disc (58) which faces the lid (18). A radially acting sealing element (62) is held on said end disc and is used to seal the non-treated area (70) of the filter element (30). The aim of the invention is to develop one such filter device in such a way that it can be economically produced and easily mounted. In order to achieve this, the sealing element (62) comprises a radial sealing lip (64) arranged on the inner side of the filter housing (12) and inclined in the direction of the non-treated area (70) of the filter element (30).

A filter insert includes a plurality of annularly-shaped, bag-type filter sleeves (111, 112, 113) concentrically-arranged. The ends of the sleeves are attached to the flanges of an inlet plate 114, an annular terminal plate 124 or a circular terminal plate 121 (e.g. by ultrasonic welding). The filter insert is removably placed within a basket such that concentrically-arranged screens (160, 161, 163) of the basket support respective filter sleeves against radial flow during filtration.
